Plot hole: Dr. Quest is speaking through the Dragonfly's speakers to the Po-Hos as they fly over the jungle, telling them he is their air God and is angry the tribe has taken hostages. Quest could have told the Po-Hos to just release the hostages, rather than putting himself in danger later on by getting captured.
